Quick Answer: GameLoop offers official optimization and true 120 FPS capability through specific configuration steps, while BlueStacks provides superior customization features but requires more system resources. GameLoop wins for competitive performance, BlueStacks excels in versatility and multi-instance gaming.
Let's cut through the marketing noise here. After spending countless hours testing both emulators across different hardware configurations, I can tell you the 120 FPS question isn't as straightforward as either company wants you to believe.
The Real Deal: Official vs Third-Party Status
Here's what actually matters in this comparison. GameLoop isn't just another emulator – it's Tencent's official baby, built specifically for their games. This means they've got direct access to PUBG Mobile's code, the proprietary AOW engine, and can push updates that sync perfectly with game patches. We're talking 24-48 hour turnaround times here.
BlueStacks? Different beast entirely. They're the Swiss Army knife of Android emulation, supporting thousands of apps with features GameLoop can't touch – multi-instance gaming, macro automation, the works. But here's the catch: they're always playing catch-up with game-specific optimizations.

The PUBG Mobile 4.0 compatibility story tells you everything. GameLoop gets optimization patches almost immediately through their direct pipeline with Tencent. BlueStacks relies on community feedback and reverse engineering – still effective, just slower.
120 FPS: Let's Talk Reality
Can your rig actually handle true 120 FPS? Most people asking this question are setting themselves up for disappointment.
You'll need serious hardware:
CPU: Intel Core i5-8400 or AMD Ryzen 5 2600 minimum (6 cores, no compromises)
GPU: NVIDIA GTX 1060 6GB or AMD RX 580 8GB
RAM: 16GB DDR4 with 8GB dedicated to the emulator
Storage: NVMe SSD with 50GB breathing room
Even with this setup, 120 FPS often means brief spikes rather than sustained performance. The emulator engines themselves create bottlenecks that mobile hardware simply doesn't face.
GameLoop's AOW engine does something clever – it bypasses standard Android rendering through direct hardware acceleration. Think of it as a shortcut that skips unnecessary translation layers. BlueStacks uses generalized Android virtualization, which is more compatible but introduces overhead. It's the difference between a dedicated highway and city streets.
GameLoop's 120 FPS Workaround (Yes, It's Complicated)
This is where things get interesting. GameLoop's 120 FPS isn't just a settings toggle – it's essentially a hack that tricks the game into thinking you're running on specific high-refresh mobile devices.
Here's the exact process (and yes, you need to follow this precisely):
Device Spoofing: Change your mobile phone model to 'Samsung SM-X910' in GameLoop settings
Process Cleanup: Hunt down and terminate any background GameLoop process with Chinese characters in Task Manager
Custom Shortcut: Navigate to TxGameAssistant > ui folder, create desktop shortcut from 'AndroidEmulatorEn.exe'
Launch Parameters: Right-click shortcut, Properties, add ' .vm 100' to the Target field
Controlled Launch: Use your modified shortcut, click 'Cancel' when it tries switching to 'ASUS_I001DA'
Final Activation: In-game Graphics settings, select 'Ultra Extreme' under Frame Rate
Does it work? Absolutely. Is it stable? That's... more complicated.

BlueStacks: The Customization King
BlueStacks 5 brought some serious improvements. Hyper-V compatibility was huge – no more choosing between Docker and gaming. The resource management overhaul actually works, and their Shooting Mode feels natural for FPS controls.
But here's what I really appreciate: granular control. OpenGL vs DirectX selection, custom resolution scaling, CPU core allocation up to your system's maximum. GameLoop gives you presets; BlueStacks gives you a control panel.
The multi-instance feature is genuinely useful if you're managing multiple accounts or want to run other apps simultaneously. Try doing that with GameLoop – you can't.
Performance Reality Check
Testing on my Intel i7-10700K, RTX 3070, 32GB RAM setup:
GameLoop consistently hits 85-95 FPS with occasional spikes above 110. The 120 FPS workaround does reach target frame rates, but introduces micro-stutters and occasional crashes. Resource usage stays reasonable at 4-6GB RAM and 40-60% CPU.
BlueStacks maintains 70-85 FPS with better frame pacing. Less impressive peak numbers, but the experience feels smoother. Trade-off: 6-8GB RAM allocation and 50-70% CPU usage.
Which feels better? Honestly depends on your priorities. Raw numbers vs consistency.
System Requirements: Don't Cheap Out
GameLoop's minimum specs (dual-core 1.8 GHz, 3GB RAM) are laughably optimistic for actual gaming. Their recommended specs (Core i3 2.6 GHz, 4GB RAM, GTX 660) will get you 30-40 FPS on low settings.
For real 120 FPS gaming, you're looking at RTX 3060 or RX 6600 XT minimum. RTX 3070 or RX 6700 XT if you want headroom for maximum settings. VRAM matters too – 6GB handles 1080p, but 1440p needs 8GB+.
Input Lag: The Competitive Factor
This is where GameLoop's official status shines. 15-25ms input lag with hardware-accelerated processing. BlueStacks sits at 20-30ms, which sounds close but feels different in competitive scenarios.
That 5-10ms difference? It's the gap between landing shots and watching enemies escape around corners.
Setup Optimization (The Stuff That Actually Matters)
GameLoop Power User Settings:
Rendering Mode: Smart Mode with Render Cache (ignore the marketing, this works)
Memory: 50% of total system RAM, no more
Resolution: 1024x576 for pure performance, 1920x1080 if your GPU can handle it
CPU Cores: Maximum available
BlueStacks Pro Configuration:
Graphics Mode: OpenGL for dedicated GPUs, DirectX for integrated
CPU Allocation: 4+ cores (diminishing returns after 6)
RAM: 4-6GB standard, 8GB+ for multi-instance
Enable virtualization in BIOS (seriously, check this first)
Troubleshooting the Inevitable Issues
FPS drops usually come from thermal throttling or memory leaks. Enable Windows Game Mode, disable automatic updates during gaming sessions, and monitor your temperatures. Clear emulator cache weekly.
Black screens or initialization failures? Disable Hyper-V through Windows Features. Use Display Driver Uninstaller (DDU) for clean graphics driver installations. Set your power plan to High Performance – Windows' balanced mode throttles performance more than you'd expect.
The Verdict: Choose Your Fighter
GameLoop wins for pure PUBG Mobile performance. Official optimization, lower system requirements, and that 120 FPS capability (however finicky) give it the edge for competitive players. If PUBG Mobile is your primary game, this is your emulator.
BlueStacks excels at everything else. Multi-instance capabilities, broader app support, advanced customization, and superior stability make it the better choice for casual players or anyone running multiple games.
The performance crown goes to GameLoop, but BlueStacks offers better value for most users. Your hardware and gaming habits should drive the decision.
FAQ: The Questions Everyone Actually Asks
Can both emulators actually achieve 120 FPS? GameLoop can through device spoofing and launch parameter tricks. BlueStacks caps at 60 FPS natively but maintains it more consistently. Both need RTX 3060+ graphics cards for reliable high frame rates.
Which uses fewer resources? GameLoop is more efficient at 4-6GB RAM and 40-60% CPU usage. BlueStacks demands 6-8GB RAM but handles multitasking better.
Will I get banned for using emulators? No. Both are officially recognized by PUBG Mobile's anti-cheat system. Emulator players match against other emulator users. Bans come from actual cheating software, not legitimate emulator use.
How do I fix constant FPS drops? Enable BIOS virtualization, allocate sufficient RAM (4GB+ GameLoop, 6GB+ BlueStacks), install on SSD storage, update graphics drivers. Set High Performance power plan and monitor system temperatures during gaming.
Which has better graphics quality? GameLoop offers exclusive visual optimizations through official Tencent integration. BlueStacks supports broader customization including custom shaders and post-processing effects – different approaches, both effective.
Are keyboard and mouse controls good on both? Both provide comprehensive K&M support with customizable mapping. GameLoop offers Smart Controls with automatic binding, BlueStacks features Shooting Mode and macro capabilities. Input lag: 15-25ms GameLoop, 20-30ms BlueStacks – noticeable in competitive play.
